TWlSTER-HQEAD FOR TOOL-HANDLES.

SPECIFICATION forming part of Letters Patent No. 513,481, dated January 30, 1894.

Original application filed .T une 28, 1892, Serial No. 438,288. Divided and this application filed` December 9, 1892. Serial No. 454,636. (No model.)

To all whom it may concern:

Be it known that I, NEWTON OHAsE,a citizen of the United States, residing at Fort Scott, in the county of Bourbon and State of Kansas, have invented certain new and useful Improvements in Twister-Heads for Tool- Handles; and I do hereby declare the follow-- ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to a twisting head designed to be attached to the end of the handle of a hammer or hatchet; and it forms a division of an earlier application iiled by me on the 28th day of June, 1892, Serial No. 438,288.

The object of my invention is to provide, a simple and cheap head adapted to be attached to one end of a tool handle and designed to effect the clinching or twisting of the pointed ends of nails ot' any diameter, from the smallest size to the largest sized nail. Difficulty has heretofore been experienced by Workmen in clinching nails, particularly wire nails which are uniform in diameter except at the entrance points thereof; but by my improved twister head the workman is enabled to effectually clinch or twist the inner end of any sized nail in avery easy and expeditious manner.

To the acccomplishment of the foregoing objects, I provide a twister head having a slot which opens through one edge of the head, and with one, two or more transverse apertures, of the same or different sizes. The end of a nail can be easily fitted in the slot or one of the apertures in the twister head, and by turning or manipulating the tool or head the end of the nail can be clinched or twisted very easily.

The accompanying drawings fully illustrate my improvement, in which* y Figure 1 is a sideelevation of my twister head appliedv to a tool. Fig. 2 is a sectional view through the tool-handle and the shank of the twister head showing one means for attaching the shank to the end of the tool handle. Fig. 3 is a View corresponding to Fig. 2 but showing a different method of attaching the shank of the twister head to the toolhandle. Fig. 4 is'a detail view of a modified construction of the twister head, showing the same provided with openings, of different diameters.

Like letters of reference denote like parts in all the figures of the drawings.

D designates the twister-head forming the subject of my invention. This head is provided with a shank d which extends substantially at right angles to the length of the head D, and said twister head is further provided with a slot d and with one or more transverse apertures d. This slot d extends longitudinally of the twister-head D and substantially at right angles to the length of the shankd, and the outer end, of this slot d opens or extends through one edge of the `twister head, to enable the ends of nails to be readily fitted in the slot d and to free or remove the headD from the nail when the end of the latter has been twisted and clinched.

The transverse aperture d is provided in the twister-head at one side of the inner terminal ends of the slot d', but I do not confine myself to the use of a single aperture in the twister head, as two or more apertures can be provided in the twister head Without touching the slot or weakening the strength of the twister head. InA practice, I make the transverse apertures d of diiferent diameters, and the width of the slot d is different from the diameter of the apertures-as, for instance, the slot may be made of a width suitable to receive and clinch ten-penny nails. One of the apertures may be large enough to receive large nails, and the other aperture made small to receive small-sized nails; but the proportions can be varied or changed without departing from the spirit or sacrificing the advantages of my invention.

The twister-head may be cast in a single piece of metal, or it may be made of steel for great strength and durability.

The twister head can be manufactured and sold on the market as an article of commerce, as it is adapted for use in connection with any kind of a tool; but in the accompanying drawings I have shown the twister head applied to the end of a handle of a hatchet or hammer although I do not restrict myself to the use of thetwister-head in connection'with these particular kinds of tools.

As one means for fastening the twister head to the end of the tool handle, I may provide the shank d with an interior socket e to receive the tenon e on the end of a tool handle as in Fig. 2; but this is not material as thel twister head can be fastened to the handle in the manner shown by Fig. 3, in which the shank is made solid and driven into the end of the tool handle, a ferrule f being fitted around the end of the tool handle to prevent the same from splitting and thus materially reinforce the connection between the twister head and the end of the tool handle.

The manner of using and advantages of my improvement will be readily understood and appreciated by those skilled in the art to which the invention relates.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. As a new article of manufacture, a twister ing slot d forming the grasping jaws which n lie at right angles to theline of the attaching shank and are adapted to twist a nail point as the head D is turned or twisted around, and a nail-receiving aperture as and for the purposes described.

2. As anew article of manufacture, a twister head D for clinching nails having an attaching shank, a narrow nail receiving slot d which extends through one edge of the head at right angles to said shank and forms two contiguous grasping jaws adapted to twist a nailpoint, and transverse nail-receiving apertures of different diameters in said head D, for the purposes described, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

NEWTON CHASE.
